SIT

Raise or lower the seat to ensure your thighs are parallel to the

floor with your feet flat on the floor or a footrest.

Adjust seat pan depth to maintain two inches of clearance

between the back of your knees and the front edge of the seat.

Adjust backrest height to comfortably fit the small of your back.

Adjust the recline tension, if necessary, to support varying degrees

of recline throughout the day. Avoid the use of recline locks.

Lean back and relax in your chair to allow the backrest to

support your upper body.

TYPE

Use an articulating keyboard support and position it 1 to 1.5

inches above your thighs. Angle the keyboard away from your

body to keep wrists straight while typing. Rest your palms—not

your wrists—on a palm support.

MOUSE

Position your mouse close to the keyboard or over the numeric

keypad to minimize reaching. Avoid anchoring your wrist on the

desk. Instead, glide the heel of your palm over the mousing

surface and use your entire arm to mouse.

VIEW

Position the monitor at least an arm’s length away with the top

line of text at or slightly below eye level. Tilt the monitor away

from you so your line of sight is perpendicular to the monitor.

ILLUMINATE

Position a task light to the side opposite your writing hand.

Shine it on paper documents but away from computer monitors

to reduce glare.

ALIGN

Align the monitor and spacebar with the midline of your body

and arrange frequently used work tools within easy reach. Prop

reference documents between your body and the monitor with

an in-line document holder.

REST

Take two or three 30- to 60-second breaks each hour to allow

your body to recover from periods of repetitive stress.
